No direct regret survey exists for either side of this decision, so both numbers here are proxies — and the proxies measure desire and distress, not regret. The Gallup World Poll migration module finds that 15% of the world’s adults — more than 750 million people — would move permanently to another country if they could. Desire is concentrated by region: 33% in Sub-Saharan Africa and 27% in Latin America and the Caribbean, but only 8% in South Asia and 7% in Southeast Asia. The 33% upper-bound regional figure is used as the inaction-side proxy. Crucially, Gallup never asks non-migrants whether they regret having stayed — wanting to leave is not the same as regretting the choice to remain. The World Bank’s migration data shows why the foregone opportunity is real: the World Bank estimates that migrants’ incomes increase three to six times when they move from lower- to higher-income countries.
On the action side, a PMC-indexed mixed-methods study of Nepali migrant workers in Gulf states documented hardship rather than regret: 35% reported verbal abuse, 25% reported mental-health problems, and 42% suffered minor illness such as cold and fever — yet almost one-third (30%) intended to migrate again, which cuts directly against a regret reading. That study reports no regret rate at all. The action-side number uses its 35% verbal-abuse prevalence as a hardship/distress proxy. A second peer-reviewed study of 502 Nepalese migrant workers (PLoS One, 2023) corroborates elevated psychological distress at lower magnitude: 14.4% had mild-to-severe depression and 14.1% had poor psychological wellbeing on the WHO-5 index. These are distress proxies, not regret; many migrants report hardship alongside a firm belief that migration was the right decision — and a willingness to do it again.
With the action-side distress proxy (~35%) and the inaction-side aspiration proxy (~33%) landing within two points of each other, the gap is too small and too proxy-laden to support any directional claim about which choice people regret more. The honest reading is that this entry has no reliable direct-regret estimate on either side: one number is a verbal-abuse/hardship prevalence, the other a desire-to-migrate rate, and neither asks the regret question. The choice is also often constrained by structural factors — debt, visa availability, family obligations — that make “regret” an oversimplification of a decision that was rarely fully free.

Among Nepalese migrant workers in GCC countries, 35% reported facing verbal abuse, 25% reported mental-health problems, 42% the minor illness of cold/fever; almost one-third (30%) intended to return to GCC countries for work
抜粋
“"More than one third of workers (35%) reported facing verbal abuse, followed by emotional and physical abuse... The most common issues were minor illnesses such as a cold and fever (42%), followed by mental health problems and back pain (both accounting for 25%)... almost one-third (30%) intended to return to GCC countries for work."

Mixed-methods study of Nepalese migrant workers in GCC countries (PMC10090227). Replaces PMC6399459 which resolved to an unrelated C-reactive protein / oral cancer article. IMPORTANT: this study does NOT report any percentage of migrants who regret migrating; 30% intended to re-migrate (willingness to go again), which cuts against a regret framing. The 35% action-side proxy rate is the verbatim verbal-abuse prevalence from this study (35% of workers reported verbal abuse at work) -- a documented hardship/distress proxy, not a regret measure. This figure replaces a previously cited Gallup Global Emotions "35% high stress in past 12 months" statistic, which could not be located in that report (Global Emotions measures next-day negative experience country-wide, with no migrant-subgroup 12-month stress figure). This source also documents the broader hardship mechanism -- abuse, mental-health erosion (25%), illness (42%) -- behind the distress proxy, not a regret rate. regret_rate = 0.35.

Among 502 Nepalese migrant workers to Gulf and Malaysia, 14.4% had mild to severe depression, 4.4% had moderate anxiety, and 14.1% had poor psychological wellbeing (WHO-5 score below 13)
抜粋
“"The results suggested that 14.4% had mild to severe depression while 4.4% had a moderate level of anxiety... the WHO5 wellbeing index score suggested that 14.1% of the respondents had a score below 13, which is suggestive of poor psychological wellbeing."

Cross-sectional study of 502 Nepalese migrant workers screened at Tribhuvan International Airport (May-June 2019) using validated instruments (Beck Depression Inventory, Beck Anxiety Inventory, WHO-5 Wellbeing Index). Corroborates the hardship/distress picture on the action side: 14.4% depression, 4.4% moderate anxiety, 14.1% poor psychological wellbeing. This is a distress proxy, not a regret measure -- the study does not ask migrants whether they regret migrating. It replaces a previously cited Gallup Global Emotions "35% high-stress" statistic that could not be verified in that report. The action-side rate (0.35) is anchored to the verbatim 35% verbal-abuse prevalence in the PMC10090227 study above; this peer-reviewed morbidity study supports the same direction at a lower magnitude.
15% of the world's adults (more than 750 million people) say they would like to move permanently to another country if they could; the highest regional desire rate is Sub-Saharan Africa at 33%, then Latin America and the Caribbean at 27%, while South Asia is 8% and Southeast Asia 7%

“"15% of the world's adults -- or more than 750 million people -- say they would like to move to another country if they had the opportunity."

Gallup's migration module asks only whether respondents would move permanently if they could -- it does NOT ask non-migrants whether they regret not migrating, and contains no "follow-up aspiration regret question" (the prior excerpt's 40-55% range and 48% foregone-migration-regret figure were fabricated and have been removed). The inaction-side proxy now uses the highest real regional desire rate, Sub-Saharan Africa at 33%, as an upper-bound aspiration figure for high-migration-sending regions. This is a desire/ aspiration proxy, NOT a regret measure: wanting to move is not the same as regretting having stayed. regret_rate = 0.33.

The World Bank's wage-premium data (3-6x) establishes that the foregone opportunity for non-migrants is large and objectively verifiable. It does NOT measure regret -- it only shows the upside that drives the desire-to-migrate aspiration captured by the Gallup source. URL updated from the dead topic-overview page to the canonical "Moving for Prosperity" report, which contains the verbatim wage-gain figure.
注意事項
Neither side has a direct regret survey; both numbers are proxies that measure something other than regret, and the ~2-point gap between them is not meaningful. The inaction-side figure is Gallup's desire-to-migrate rate (33% in Sub-Saharan Africa, the highest region) -- it captures desire and revealed preference, not retrospective regret about not having moved, and Gallup never asks non-migrants whether they regret staying. The action-side figure is the 35% verbal-abuse prevalence from the Nepalese- migrant study (PMC10090227) -- a hardship/distress proxy, not a regret rate, and the study does not ask migrants whether they regret migrating. That same study reports 25% mental-health problems and 42% minor illness but no regret rate -- and 30% of those workers intended to migrate again, which argues against treating their experience as regret. A second peer- reviewed study (PMC10631658, n=502) corroborates elevated psychological distress at a lower magnitude (14.4% depression, 14.1% poor wellbeing). Migrants are geographically dispersed, language barriers impede survey access, and immigration status creates response suppression, which is why no direct regret survey exists. The decision is often less than fully voluntary: economic necessity, family debt, or employer contracts compress the choice set in ways that make "regret" an imprecise frame. This entry is distinct from flee-conflict-zone-vs-stay (conflict-driven displacement) and move-abroad-vs-stay (general international relocation for largely affluent movers); it covers voluntary economic migration from lower-income countries, primarily South and Southeast Asia, Sub-Saharan Africa, and Latin America to higher-income destinations.
